【问题描述】：

我使用 Qt Designer 创建了一个界面，并使用 PyQt5 将其集成到我的 python 代码中。然后我使用 Pyinstaller 创建了一个 exe 文件，界面在使用 Windows 10 Home 的笔记本电脑上显示良好。然而，在使用 Windows 10 Pro 的不同 Windows 机器上进行的测试显示按钮和标签全部被剪掉，字体错误，如下图所示。例如，顶部标题应为 GEODISTANCE CALCULATOR'，但仅显示“GEODISTANCE CA”。是什么导致了这种不兼容，我该如何解决这个问题？

我有下面的示例代码供任何想要测试样本的人使用：

from PyQt5 import uic, QtWidgets
import sys

app = QtWidgets.QApplication(sys.argv)

window = uic.loadUi('interface.ui')
window.show()

sys.exit(app.exec_())

从Qt Designer派生的ui文件的完整代码如下所示，可以通过将代码复制并粘贴到文本编辑器并将文件保存为'interface.ui'来重新创建文件：

【问题讨论】：

提供minimal reproducible example

@eyllanesc 当然我已经用一个例子更新了这个问题

【参考方案1】：

通过添加更多代码行来解决此问题，如下所示。有人已经发布了这个答案，但他们删除了它可能认为这是错误的，因为我花了一段时间才回复他们结果，所以谢谢！

from PyQt5 import uic, QtWidgets
import sys

# Enable high DPI scaling
if hasattr(QtCore.Qt, 'AA_EnableHighDpiScaling'):
    PyQt5.QtWidgets.QApplication.setAttribute(QtCore.Qt.AA_EnableHighDpiScaling, True)

if hasattr(QtCore.Qt, 'AA_UseHighDpiPixmaps'):
    PyQt5.QtWidgets.QApplication.setAttribute(QtCore.Qt.AA_UseHighDpiPixmaps, True)
app = QtWidgets.QApplication(sys.argv)

window = uic.loadUi('interface.ui')
window.show()

sys.exit(app.exec_())
